                                <h3>题目描述</h3><p><p><span style="font-size: medium">要求在平面直角坐标系下维护两个操作： <br />
1.在平面上加入一条线段。记第i条被插入的线段的标号为i。 <br />
2.给定一个数k,询问与直线&nbsp;x = k相交的线段中，交点最靠上的线段的编号。&nbsp;&nbsp;<br />
</span></p></p><hr/><h3>输入格式</h3><p><p><span style="font-size: medium">&nbsp;<br />
第一行一个整数n，表示共n&nbsp;个操作。 <br />
接下来n行，每行第一个数为0或1。 <br />
&nbsp;<br />
若该数为&nbsp;0，则后面跟着一个正整数&nbsp;k，表示询问与直线&nbsp; <br />
x = ((k&nbsp;+lastans&ndash;1)%39989+1)相交的线段中交点（包括在端点相交的情形）最靠上的线段的编号，其中%表示取余。若某条线段为直线的一部分，则视作直线与线段交于该线段y坐标最大处。若有多条线段符合要求，输出编号最小的线段的编号。 <br />
若该数为&nbsp;1，则后面跟着四个正整数&nbsp;x0, y0, x 1, y 1，表示插入一条两个端点为 <br />
((x0+lastans-1)%39989+1,(y0+lastans-1)%10^9+1)和((x<br />
1+lastans-1)%39989+1,(y1+lastans-1)%10^9+1) 的线段。 <br />
其中lastans为上一次询问的答案。初始时lastans=0。&nbsp;<br />
&nbsp;<br />
&nbsp;</span></p></p><hr/><h3>输出格式</h3><p><p><span style="font-size: large;">对于每个&nbsp;0操作，输出一行，包含一个正整数，表示交点最靠上的线段的编</span><font size="4">号。若不存在与直线相交的线段，答案为0。 <br />
</font></p></p><hr/><h3>样例输入</h3><pre>6 
1 8 5 10 8
1 6 7 2 6
0 2
0 9
1 4 7 6 7
0 5
